How Do You Convert EU Shoe Size to US?
Convert shoe sizes between EU, US Men's, US Women's, UK, and foot length in centimeters. Our free shoe size converter instantly translates between all major sizing systems so you can buy footwear from any country with confidence.
How it works
Shoe sizing systems differ by country and gender. EU sizes use a numeric scale (36–47 for adults), US sizes use a different scale with separate men's and women's ranges, and UK sizes are close to US Men's but shifted by half a size. All systems can be converted through EU size as a common reference. Sizes shown are approximate — fit can vary by brand and style.

How do I measure my foot size at home?
Stand on a piece of paper, trace around your foot, then measure the longest distance from heel to toe in centimeters. EU size ≈ foot length in cm × 1.5 + 2, or look up a size chart. Feet are often slightly different sizes — always fit to the larger foot. Feet also tend to swell during the day, so measure in the afternoon.
What EU shoe size is a child's US size 3?
US children's size 3 corresponds to approximately EU 35. Children's sizing varies more by age and brand than adult sizing. For growing children, a thumb's width (about 1 cm) of space at the toe is recommended to allow for growth without the shoe being so large it causes tripping.
Are shoe sizes the same for running shoes and casual shoes?
Not always. Running shoes are often recommended in a half-size to full size larger than casual shoes because feet swell during exercise and you need toe clearance when running downhill. Boots may require a half size up if worn with thick socks. Always try on athletic footwear with the socks you intend to wear during activity.
